Application filed April 6,

170 all whom it may come r12;

Be it known that 1, Jon 5. KoUnoL, a citizen of the United States,residing at Cuba. in the county of Republic and State of Kansas, haveinvented certain new and useful improvements in Emery-Wheel Stands, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to a grind stone or cniery wheel vstand and hasfor its object to provide a device of this character wherein one or moregrind stones or emery wheels can be attached and operated simultaneouslyto abrade different articles at the same time.

Another object is to provide a device of this character including meansfor holding tools in position before the einery wheel.

A still further object of the invention is to provide means whereby aharrow disk may be positioned and edlciently sharpened, said meanspermitting rotation of the disk over the periphery of the rotatingeinery wheel at the desired inclination.

With these and other objects in view, the invention consists in theimproved construction and arrangement of, parts to be hereinafter moreparticularly described and more fully claimed and illustrated in theaccompanying drawings, in which:

Figure 1 is an end elevation of the emery wheel stand,

Figure 2 is a side elevation,

Figure 3 is a top plan view,

,Figure 1 is a section taken on the line 4-4 of Figure 1,

Figure 5 is a front elevationof the gear housing,

Figure 6 is a tool rest applied,

Figure 7 is a detailed sectional view of the tool rest,

Figure 8 is an end elevation of the saw attachment,

Figure 9 is a side elevation of the structure shown in Figure 8, and

Figure 10 is a perspective view of one of the brackets of the saw table.

Referring to the drawings, 5 designates a stand including standards 6and 7 ,the upper ends of each pair of standards 6 and 7 being connectedto the ad acent standards by means of a bearing block 8. The feet orlower ends of the standards are secured to skids 8 which permitthe standto be used side elevation showing the Serial No. 459,044.

on soft ground. A shaft 9 is .rotatably mounted .upon' the bearing blocki8, a hearing plate 10 being disposed over the shaft and upon thebearing blocks 8 to maintain the shaft in position. Theends of.the-shaft 9 extend beyond the standards and rare intended to receivegrind stones or emery wheels 11, the wheels being disposed in spacedrelationto thestandards to prevent contact of the article 'beingcabradedwith the stand. A conventional formofpulley 12 is secured =totheintermediate portion of the shaft 9 and is .adapted tobe connected toa source of power.

In order to permit the efficient .abra ding of tools, there is provideda novel forrnv of tool rest consisting of a bar 13 which is secured .toone end of the. stand, that is, vone end of the bar is secured to one ofthe standards 7 and the opposite end portion to one of the standards 6.One end of the bar is bent back upon the main position of the bartoprovide an arinltv which serves to space the tools to be sharpenedfrom the standards. The arm 14L is provided with a slot 15 adapted toreceive the U-shaped clamp 16, bolts 17 being carried by the end of theclamp to ,perrnitadjustmentrand tightening of the same. A tool support17 is used, said support being substantially L-shaped. The end portion.18 of the support'is, adapted to be secured b'ya suitable clarnp 9t0the stand, whilethe end portion 19 of the support is extended throughthe clamp 16. and is secured to the arm 1% substantially in a verticalposition, the extremity of the end portion 18 being provided with asocket 20'for the reception ofa tool rest 21. An importantifeatureof'thissupport is'that it can be naintained at various positions in viewof thefact that the slot 15 is made relatively "long so that the clamp16 may be adjusted longitudinally of the arm 14. In addition to this,the end portion 19 of the standard may be moved to variousinclinedpositions,so that any form of toolinay be 'eflicient-ly abradedwith the use of this support.

In order to sharpen 'h'arro w disks, cultivatorshovels and likeimplements, there is provided a novel fo'rrnof support comprising a bar22adapte'd to extend across the stand and secured thereto by means ofclamps 23 which permit oscillating movement of the bar. "The end portion24 of the bar is extended at rightanglest'o said bar and provided withan opening for the reception of the set screw 26. The set screw 26 isadapted to be disposed in one of a series of openings 27 formed in asegmental member 28. The end 29 of the segmental member is secured toone of the stands, while the end 30 issecured to the bar 13. By thismeans, the bar 22 may be adjusted and secured in various positionsaccording to the inclinations desired for sharpening a particularimplement. The opposite end 31 of the bar is extended in the oppositedirection to that of the end 24, and then back upon the bar to providean .arm 32 which is positionedsubstantially in spaced parallel relationto the bar. A pair of U-shaped clamps are secured to the arm 32, andhave their ends connected by means ofbolts 34, the purpose of which willbe hereinafter described.

"A separable housing is adapted to be disposed between the clamps 33,the meeting edges of the housing being'maintained substantially at rightangles to provide cars adapted to be disposed between the ends of theclamps 33 and to be secured by means of the bolts 34s By this means, theclamps not only serve to connect'the housing to the arm :32, but alsoprovide means for holding the separable positions of the housings inengagement with each other. A gear 36 is mounted within the housing andis adapted to engage a worm gear 37 mounted in a supplemental housing 38carried by one of the separable portions of the housing 35, the wormgear 37 including a shaft 39, and hav a handle 40' on one end thereofthrough the medium of which the gear 36 is rotated. A handle 4C1v issecured to the housing 38 and is disposed at right angles to the shaft39 and housing 35. The shaft 36 on which the gear 36 is mounted projectsbeyond the housing 35 and is threaded. A disk A is intended to bedisposed upon the shaft 36" and secured by means of a nut 42 including ahandle. In use, after the disk has been attached to the shaft 36, thehousing is moved toward the emery wheel through the medium of the handle41 and the clamps 33. In view offthe distance between the arm 32 and thestand, the diskwill be maintained in an inclined position. This positionmay be regulated by adjusting the end 24L of the segmental member 27.The operator holds the disk in engagement with the emery wheel throughthe medium of the handle 41, and at the same time rotates the gears andthe disk A through the medium of the handle 40, the emery wheel beingrotated by independent means. By this arrangement, all

portions of the disk receive the same amount When the disk has beensharpened, the housing may be moved away from the emery wheel throughthe medium of thehandledl and the disk A removed.

and substituting a saw blade 4:2 To properlyrsupport timber before theblade there is provided a noveltable structure embodying a U-shapedbracket 43, the ends of the arms of the bracket having arcuate recesses44 adapted to engage the bar 22 of the-bar 13. Thearms of the bracketsare also provided with recesses 45 adapted to engage the arm 32 of thebar 22 or the arm ll'of the bar13. This bracket is intended to supportone end of a table 416. The'opposite end of the table is supported bymeans of a bracket 4.? which is secured to one of the standards. Thetable it; is provided with a slot through which the saw projects. Atimber guide 48 is'mounted on the table adjacent the saw blade;

From the foregoing it will be readily seen that this invention providesa novel form of grind stone and emery wheel stand whereby any deviceregardless of its shape or size, may be readily positioned for abradingor sharpening, and wherein two per sons may use the device at thesametime. By the novel inclinations of the standards 6 and i', and the skids8, the operator may apply the desired weight against the article to betreated without danger of tilting the stand. I

What is claimed is:

1. A device of the character described, comprising a stand, a rodjournaled on the stand, one end of said rod being adapted to engage amember having a series of openings, the opposite end of the bar beingextended back upon the bar, gear meansmovably connected to the lastmentioned end of the bar, means for securing an implement to the gearmeans, andmeans for rotating the gear means andfor moving the sametoward the abrading means. i

.2. In combination with a stand, abrading means mounted on the stand, asupporting bar mounted on one end portion of the stand in spacedrelation to the abrading means, a shaft rotatably mounted on one side ofthe stand, means for operatively connecting said shaft to the connectingbar, one end of said shaft being provided with tool supporting means, asecond shaft mounted on the opposite side of the stand, means foradjust-ably connecting one end portion of the second mentioned, shaft tothe connecting of the shaft, a supporting bar mounted on and extendinglongitudinally of the stand,
